Heat-regulator for brooders.



HEAT-REGULATR FOR 31100D3125.

Speccationc Letters Patent.

tain new and useful Improvements inHeat- Regulators for Broeders, of which the tollowing is a. specification.

ln heating a' broeder it has been 'found dillicult to utilize the steady heat of the coal owing to the liability of the escape of.

coal gas which is deadly to chicks and it' for this reason that many'other types of less' desirable heat have been used.

'The object or" my invention is to providea coal stove tor heating broeders of such ,:onstruction that the liability of the escape of ooalgas is entirely eliminated..

further lobject of my invention is to n vide means for maintaining anypredetei nined temperature in the vbroeder lautomatically; and with these `objects in view any invention consists of the/parts and comhi nation of parts as will be hereinafter more fully pointed out. s

.ln the drawingsrFigure l 1s a central vertical. section through a stove and broeder i embodying a heatg'regiilating mechanism. Fig. 2- is a top plan viewiof the same` the broeder hood being partly broken away.

The reference numeral-1 vdesignates the body of a stove having aL fire box 2 and an ash pit or chamber A3, all of which may be of any approved construction. The ash pit er chamber is provided with an -ash door 4 and an air door The top 6 of the stove is et relatively largearea andis provided with a. iuel opening. central with the fire box.y the walls of which are beveled as at .8, and an opening 9 also communicating with the lire box, thel wall of the stove being deflected as at- 10 under said opening 9.:v The periphery otlithe top 6 isv provided with a depending annular flange 1l set at an angle less than a right angle.

i9 is a hood open at the'top and bottom,4

the side walls of .which are formedoii the same 'angle as vthe flange 11 yso aste form therewith a tight. joint.v

13 is an inwardly extending top marginal flange integral with the hood and-adapted to rest upon the top 6 of the Stoveand assist in supporting 'the hook-vin' the position' shown.

lllare cords or chains adapted torun over pulleys for the purpose of raising the hood.

Patented Sept. "l, illll Application filed December 19, 1914. Serial No. 878,l)94

Mounted upon the iopD 6 are twoichanibcrs l5 and 1G. The chamber 15 being a gas chamber over the fuel openiiigand the mags4 azine ll', said magazine being removably suspended from the top G in the firefbox, and provided with a flaring top in which is seated a valve 18 having an operating haiidle which passes through a relatively large opening in thecover 2O of the chamber l5.

The chamber 1G Iis positioned overthe smoke opening or passage 9 and is separated from the cl-ianiber l5 by iiicans of a partition 21 having perforations Q2 to establish :onimunica tion between the two chambers whereby saidchainbers are always in communication with the vflue 23 whereby any that may escape from the stove into these chain! bers is drawn up the flue by a natural draft.` The smoke chamber is provided Awith an air door 2li, and is also provided with a `damper seat on which the, damper 25 is A substantially bell crank lever is keyed to the shaft 27, the upper portion of the arm 28 of which is deflected and flexibly connected withthe door 24 of the smoke chamber by mezins of a chain 29. The arm 30 ot said bell cranllr lever is pivotally connected with the upper end of the rod V31.

A :traine 32 is supported .from one side of the stove and a lever. 33 is pivotally mounted on said frame, the 'free end of this lever being attached to the lower end of the rod 31. 34 is another lever' pivotally secured at one end to the frame 31 while its other end is pivotally secured to the lever 33, the end portions of the lever 33 being deected'in opposite directions.

35 is a thermostat connected to the frame and to the lever 34. I

A chain 3G constitutes a flexible connection between the outer or free end of the ylever 33 and thoi'air door 5 of the ash pit or chamber.

Assuming that the parts are in the position shown in the drawings with all draft cut oil, any predetermined drop in the temperature of the broeder or the room in which it is located will affect the thermostat which will operate the lever 34 and through it the lever 33 causing the lever 33 to move upward at its free end, thus opening the door 5 by means-of the Chain 36, and simultaneously moving the rod 31 upward which motion communicated through the crank arm 30 to the shaft 27 which is thereby revolved toward the left and the damper 25 moved downward to open position. At the same time the crank arm 2S is swung toward the left to permit the air door 24 of the smoke chamber to move to closed position. As soon as the predetermined maximum temperature is reached the thermostat is again actuated and moves the parts to the position shown in the drawing, in which the damper 25 and air door 5' are closed while the air door 24 of the smoke chamber is open. f.

Vhen the parts are in the position shown `the pressure of the gas in the stove may which it will readily escape to the flue Q3.-

To facilitate the escape of gas into the ilue, and thereby prevent it from entering Ythe room, the air door 251. is held in open position as shown and the opening in the cover 20 is relatively larger than the handle 19 to permit air to enter the chambers thereby creating in eiect'a forced draft to carry the gases into the Hue. The cover 20 may, it' found necessary, be provided with addi# tional air openings.

As shown in Fig. l I secure to the shaft 2T of the damper, an arm 37 on which is adjustably mounted a weight 38, whereby the weight of the parts is counterbalanced thereby facilitating the action of the thermostat.

What I claim is:

l. The combination with a stove having fuel and smoke openings in juxtaposition, a chamber over each opening, said chambers being in communication with each other and in constant communication with a flue, a flue damper between one of said chambers and the stove, an air door for one of said' chambers and the stove, a bell crank lever on said damper one arm of which has an operative connection with said air door, a rod having an operative connection with the other arm of the bell crank lever, and means to operate said door and damper.

2. The combination with a stove having fuel and smoke openings in juxtaposition, a chamber for each opening, said chambers being in communication with each other and in constant communication with a flue,

LiL-saaie lue damper between one of said dampers and the stove, an air door for one of said chambers and the stove, a bell crank lever on said damper one arm of which has an operative connection with said air door, a rodhaving an operative connection with the other arm of the bell crank lever, means connected with said rod to operate it, an air door for the ash pitlof the stove and in operative connection between said ash pit air door and said means whereby both of said air doors and the damper are operated simultaneously as described. l

3. The combination with a stove, of a frame suspended from said stove, a lever pivotally mounted on said frame, a second lever pivotally mounted on said frame, at .one end and pivotally connected at its other end to the first named lever, operating means connected to said frame, and to the said second named lever, a flue damperfor said stove, and two air doors for said stove, an \operative connection between the iirst named leverand said air doors and damper whereby one of said doors is moved to open posi tion while the other of said doors is being moved to open position and whereby said damper is moved to open position simulta-v neously with the movement of doors to closed-position.

4. The combination with a Stowe having fuel and smoke openings in juxtaposition, a chamber for each opening, said chambers being in communication 'with each other and in constant communication with a flue, a iue damper between one `of said dampers and the stove, an air doorliior one of said chambersand the stove, alllbell crank lever `one of said on said damper one a'rm.v llwhlfeh has anv operative connection with sai ai door, a rod havingl an operative connection lwithV thel otherfarm of the bell crankiv le er, lmeansmoeratively connected with said od.4 to operate it, an air doorv for the ash pit yof the `stove and in operative connection between said ash pit air door and said means vih roby both of said air doors and the damv er'y are operated simultaneously as describelfd, a counterbalance weight for the partsn by the said means. l ,5 i In testimony whereof I atX my sign E I in presence of two witnesses. sf l l CLEMENT V.
